Apple unveils its quad-core A10 Fusion chip

You know how this works: Another iPhone, another entry in Apple's mobile processor lineup. The company just unveiled the iPhone 7 and 7 Plus, which are powered by its new A10 Fusion mobile processor. While last year's A9 was an astounding 70 percent faster than its predecessor, the gains this time are less about speed and more about efficiency. The A10 Fusion is just 40 percent faster than the A9 on the iPhone 6s and 6s Plus, but packs two sets of dual-cores that are designed to handle specific tasks better.

Two of the cores are what Apple calls "high-performance," which likely handle more intensive tasks such as video editing and gaming. The other two are "high-efficiency," and perform their duties at a fifth of the power the other pair does. An Apple-designed performance controller decides which cores should execute specific processes.
